PSP PianoVerb Great for piano, but I also use it for rhodes, wurli or acoustic guitar. This reverb is completely different from all other reverbs I know, some presets detune the sound a little with very interesting results. Check it out ! Well, there are some interesting eqs, compressors and other stuff for free, but since the day I have seen Wave plugins for the first time (a friend of mine has got Waves) the Freeware stuff does not satisfy me any more, even the reverbs of Waves were great !
